Next-Generation "Mid-Air Display" Technology Debuts

According to the patent granted granted to Dyner in 2005, the Heliodisplay operates “by ejecting atomized condensate present in the surrounding air, in a controlled fashion, into an invisible particle cloud.” The cloud is produced using a heat pump, according to the patent office,Â which creates a thermal differential to extract condensation from the ambient air. That condensation is pumped into an expansion chamber where it is atomized, then forced through an ejection nozzle to create a particle cloud screen. The patent also covers use of an optical system to detect and track movement in and around the mist, and using the tracking information for control functions.
